Datasheet Inhibitors / Agonists / Screening Libraries A DRUG SCREENING EXPERT Product Name : Prinaberel Catalog Number : TQ0149 CAS Number : 524684-52-4 Molecular Formula : C15H10FNO3 Molecular Weight : 271.24 Description: Prinaberel (ERB-041) is an effective and selective ERβ agonist and >200-fold selective for ERβ. Storage: 2 years -80°C in solvent; 3 years -20°C powder; Solubility DMSO ≥38mg/mL(140.1 mM) ( < 1 mg/ml refers to the product slightly soluble or insoluble ) In vitro Activity Treatment with ERβ selective estrogen agonists liquiritigenin and ERB-041 reduced the ability to invade a reconstituted basement membrane and to migrate in response to the cellular stimulus [1]. Pretreatment the PMs with ERB-041 resulted in significant inhibition of LPS-induced iNOS expression and NF-kappaB activation by preventing its nuclear translocation [3]. In vivo Activity Tumor numbers and volume were reduced by 60% and 84%, respectively, in the Erb-041-treated group as compared with UVB (alone) control. This inhibition in tumorigenesis was accompanied by a decrease in proliferating cell nuclear antigen (PCNA), cyclin D1, VEGF, and CD31, and an increase in apoptosis [2]. Reference 1.
